Subject: gen7/cmd_buffer: SCISSOR_RECT structs are tightly packed
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d3607351fecd80c5e875204af394e4aaee06754f;p=mesa.git

gen7/cmd_buffer: SCISSOR_RECT structs are tightly packed

The pointer has to be 32-byte aligned, but the structs themselves are 2
dwords each, tightly packed.
